Smith nicknamed his car 'The Shed' and said it has seen lots of adventures and mishaps

The auction was held through eBay, raising 6,300 ($9,576) for terminally ill children. The young actor bought the "pre-Tardis" car - nicknamed "The Shed" - in 2000, before he was accepted into the National Youth Theatre.

Prior to the sale, Smith said of the car: "It has seen lots of adventures, not to mention a few mishaps. I'll be very sad to see it go."
